In the shadows of Boston, Spenser (Robert Urich), a former cop with a poet's soul and a fighter's fists, solves crimes in his own uniquely stylish way. A true Renaissance man, he faces danger head-on, backed by his formidable ally Hawk (Avery Brooks) and contacts inside the police department. While he's unstoppable on the streets, his love life stalls as his longtime love (Barbara Stock) refuses to marry a man whose life is a constant dance with death.
